According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 1997 RAM 1500 has 6 documented known issues, with 2 rated critical. The most serious are 5.2L/5.9L Magnum Intake Manifold Plenum Pan Gasket Failure (Oil Burning, Misfire, Cat Damage) ($150-$600 repair) and 42RE/46RE Governor Pressure Solenoid and Sensor Failure — Limp Mode / Wrong-Gear Start ($150-$500 repair). Across all issues with published estimates, repair costs range from $50 to $3,000. DIY maintenance guides at au7o.io.
On the 1994-2001 RAM 1500, on Magnum-engine Rams the intake manifold has a stamped-steel plenum pan sealed to the aluminum manifold by a one-piece gasket. Because steel and aluminum expand at different rates, the gasket tears over time and lets engine oil from the lifter valley get drawn into the intake plenum and burned. Virtually every high-mileage 3.9/5.2/5.9 Magnum develops this. Burned oil fouls the oxygen sensors, causes detonation (pinging), and can destroy the catalytic converters if ignored.
Blue smoke / oil pooled in bottom of intake plenum
Fouled spark plugs and O2 sensors
How to Fix
Remove the intake, discard the OE stamped plenum pan and install an aftermarket billet/thicker steel plenum repair plate with a new gasket (commonly sold as a 'plenum repair plate kit', e.g. from plenumrepairplate.com), or install a Mopar/Fel-Pro intake gasket set (Fel-Pro MS 90314 series plenum/valley gaskets). Inspect and replace fouled O2 sensors afterward. DIY parts run roughly $60-$180 (gasket/plate kit); shop labor adds the rest.

Hughes Engines HUG 7720FEL V8 Magnum plenum repair kit
1992-2003 Dodge/Jeep 5.2L and 5.9L Magnum V8 only; includes aluminum plate, premium Fel-Pro gaskets, bolts and bypass hose. Not for the 3.9L V6.
On the 1994-2001 RAM 1500, the 3.9/5.2/5.9 Magnum uses a camshaft position sensor inside the distributor plus a crankshaft position sensor on the bell housing. These sensors are heat-sensitive and fail intermittently — the engine stalls or dies when hot and refuses to restart until it cools, or cranks-but-won't-start with no other symptom. Corroded/loose sensor connectors cause the same behavior.
Inspect the sensor connectors/wiring for corrosion or a pulled pin first. Replace the failing sensor with a Mopar unit (owners report frequent failures of cheap aftermarket sensors): camshaft (distributor pickup) sensor Mopar 56027868 and crankshaft position sensor 56027865 (verify by engine/year). On distributor-cam-sensor trucks a full distributor may be needed if the pickup is integral. Parts $30-$150; typical $50-$250.

On the 1994-2001 RAM 1500, the electronically-controlled 42RE/46RE automatics regulate shift points with a PWM governor pressure solenoid plus a governor pressure sensor/transducer in the valve body. These parts get contaminated by transmission varnish and wear out. When the sensor feedback no longer matches the commanded pressure, the PCM sets a code and drops the transmission into 'limp' mode — no overdrive, 2nd/3rd-gear start, harsh or no shifts. Extremely common on high-mileage 2nd-gen Rams.
Transmission stuck in limp mode (2nd/3rd gear only)
No overdrive / no lockup
Wrong-gear starts
Harsh or delayed shifts
Speedometer-related shift errors
How to Fix
Drop the pan and replace the governor pressure solenoid (Mopar 4617210) and the governor pressure sensor/transducer (56028196AD, supersession of 56041403AA); available together as an aftermarket kit (e.g. Hercoo/TransGo). Fresh ATF+4 and a filter at the same time. DIY parts ~$40-$120; shop job $150-$500. Confirms and clears P0748/P1757/P0868 limp-mode codes.

1996-1999 42RE/46RE governor pressure transducer 56041403AA family
On the 1994-2001 RAM 1500, second-gen 4WD Rams use a vacuum-operated Central Axle Disconnect (CAD) on the front axle to lock the right axle shaft when 4x4 is selected. The rubber/plastic vacuum lines become brittle and crack, the vacuum switch fails, or the CAD diaphragm/actuator ruptures — so the transfer case engages but the front axle never locks in and there's no front drive (or it won't disengage). A frequent cause of 'my 4x4 doesn't work.'
Transfer case shifts to 4x4 but no front-wheel drive
4WD won't engage or won't disengage
Grinding/no lock at the front axle
Vacuum leak / rough idle from cracked CAD lines
How to Fix
Diagnose vacuum before parts: with engine running, one line to the axle shift motor should read ~20 in-Hg and switch when the transfer case is shifted. Replace cracked vacuum lines and the vacuum switch first; replace the CAD actuator if the diaphragm is ruptured. A permanent fix is a cable-operated 4x4 Posi-Lok kit that eliminates the vacuum system. Parts $30-$200; typical repair $100-$400.

On the 1994-2008 RAM 1500, these Rams are widely known for rust-through at the rear wheel arches, lower quarter panels, cab corners, rocker panels, and the bed (inner bedside rusts out to the exterior on trucks through ~2006 due to poor drainage and moisture-trapping foam in the bed rails). It is severe and common enough that a large aftermarket of stamped repair panels exists specifically for these years.
Address early: treat surface rust, keep drains clear. For rust-through, cut out the affected metal and weld in reproduction panels — rear wheel-arch skins, cab-corner patches, rocker and bed patch panels (Raybuck, Mill Supply, Classic 2 Current). Prime, seal, and undercoat. DIY panels cost $30-$150 each; professional cut-and-weld with paint runs $500-$3,000+ depending on extent.

On the 1994-2010 RAM 1500, the in-tank fuel level sending unit (float arm and variable-resistor card, part of the fuel pump module) wears out and gives false readings — commonly reading full then dropping to empty, sticking, or bouncing. On OBD-II trucks it sets P0463/P0462. It is one of the most-searched Ram gauge complaints and is separate from the instrument-cluster fault.
Confirm the sender resistance sweep before replacing the cluster. Repair requires dropping the tank (or removing the bed) and replacing the fuel level sending unit — often done as a complete fuel pump/sender module for reliability. Avoid the cheapest unbranded senders, which frequently read wrong out of the box; use a quality module (Delphi/Spectra/Mopar). Parts $60-$250, with labor $150-$500.
